132938-26-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 132938-26-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,9,3 and 8 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132938-26:
(8*1)+(7*3)+(6*2)+(5*9)+(4*3)+(3*8)+(2*2)+(1*6)=132
132 % 10 = 2
So 132938-26-2 is a valid CAS Registry Number.
